The invention discloses an underground building pipe pile group foundation construction method which comprises the following steps: S1, foundation construction preparation including technical preparation, construction site preparation, pipe pile positioning preparation and soil layer treatment; s2, according to the pipe piles at different positions, pipe sinking cast-in-place piles, drilling cast-in-place piles and hole digging cast-in-place piles are selected; s3, forming holes in the positions of the cast-in-place piles; and S4, steel bars are bundled in the holes formed in the step S3, a formwork is poured, and concrete pouring forming is conducted. According to the distribution of the underground pipe pile group and the environment and the position of the corresponding position of the pipe pile, a reasonable pile filling method is selected, in the pile filling process, by setting the technical parameters of the pipe pile, different pile filling modes are adopted for the filling pile in different places, the construction efficiency of the pipe pile group is improved, meanwhile, the bearing capacity of the pipe pile is guaranteed, and the construction cost is reduced. The problems that the operation difficulty is increased and the bearing capacity of the pipe pile is influenced when the pipe pile operation is carried out in the same mode are avoided.
本发明公开了一种地下建筑管桩群基础的施工方法，包括以下步骤：S1：基础施工准备，包括技术准备、施工现场准备、管桩定位准备和土层处理；S2：根据不同位置的管桩，选择沉管灌注桩、钻孔灌注桩和挖孔灌注桩；S3：在灌注桩位置进行造孔；S4：在步骤S3中形成的孔中捆扎钢筋和浇筑模板，进行混凝土浇筑成型。本发明根据地下管桩群的分布和管桩对应处的环境和位置，选择合理的灌注桩方法，并在灌注桩的过程中，通过对管桩的技术参数进行设定，实现了不同地方的灌注桩采取不同灌桩方式，提高了管桩群施工的效率，同时保障了管桩的承载力，避免了采用同一方式进行管桩作业，增加了作业难度，同时影响管桩的承载力。
